Keeping www allows hosting static content in cookieless subdomain (without getting new domains) which speeds up page loading.

It is great for building up the hardware side of nation, but not "software" side. The cultural advancement is lagging behind the infrastructure improvement planned by engineers.

It is probably true for platform companies, but in the end cash still rules. With respect, I think Facebook and Tencent are the only few "egoless" big players trying to stay releva…

This tactical approach will only work in existing markets with known customers and known solutions. War is only the tool to achieve the goal, should not be the goal itself.

The valuation of Yahoo assets in Asia is about the same to the current market cap. The bold move is to focus on emerging markets and move headquarter there.

Exactly. Wish that there is an option for users to keep EXIF including geotagging. And give us API to query metadata of pictures (with privacy control).

The article is a little bit misleading. Serving a larger area and serving more people are actually conflicting goals. The latter is always more important in urban area.

As I understand, iPhones get NAT IP (10.x.x.x) in AT&T 3G networks, and outgoing IP shows the gateway location (at least some located in Los Angeles). From the article, the idea is…

In the context, I meant all users in mainland China behind GFW, not Chinese-origin users.

If Inside Facebook's statistics is based on IP, not surprised that there are only few. All Chinese users use proxy/VPN/Tor/SSH to get access from oversea IP.

Trying to setup a private cloud in China because of GFW. UEC with Eucalyptus is nice for leveraging AWS API ecosystem. Hope to make infrastructure in US (AWS) and China as similar …

It will be interested to see how Bluetooth 3.0+HS (Bluetooth+WiFi, backed by Broadcom/CSR) and WiFi Direct (My WiFi, backed by Intel) compete with each other. But I think Bonjour m…

Just found CouchDB solving peer-based replication, and it's not structural.

It will probably only work for the next-gen iPhone/iTouch if the rumor is true because the Broadcom WiFi/BT/FM chip needs separate antenna for FM TX/RX. The current WiFi/BT antenna…

Looks like wiki spreadsheets for structural data with API. Still has limitation that we can't add columns, for example latitude and longitude for restaurants. On revenue model, it …

So far Google Wave is like Google Docs with a better diff if not using extension. It will replace Google Docs before it can even replace Gmail.

Amazon (Joyo in China) don't have Chinese Kindle books. And Kindle doesn't support Chinese characters without hacks yet. With censorship on print books, China is already the bigges…

At least some people may want touchscreens for first person shooting (FPS) games if touchscreens can handle finger poking. :-)

Dr. Williamson's work is surprisedly very relevant for hackers' startups. His transaction cost economics of markets vs hierarchies explains how startups can compete or sell service…

The trouble is only for developers of native Android app. Not intended, but arguably Google may benefit even more with mess of compatibility problem because eventually only mobile …

More than crowdsourcing benenfit. Have been thinking that Open Subtitles has chance to transform movie search. Netflix could use Open Subtitles to enhance similarity ranking. Or Ap…

Honestly, it is not as useful as ultrawideband handheld radar under prototyping. Surrounding antenna array is just too excessive.
